I am new to this forum, I have a 1984 SS which just recently started to have starting problems and once started runs rough at idle and has occassional surging and skipping problems when driving at a steady speed, very noticable with A/C on. Cleaned the ERG valve with very little improvement.
Car has 72000 original miles, does not burn oil, has new plugs and wires.

Any suggestions/help would be appreciated
